你看看提示的是什么错误，就找出来了，用不着问别人的

不,提示只是说有一个错误,但没说是什么错误

--------------------Configuration: good - Win32 Debug--------------------
Compiling...
good.cpp
D:\wy\fish\good\good.cpp(105) : error C2065: 'sprt' : undeclared identifier
Error executing cl.exe.

good.exe - 1 error(s), 0 warning(s)

明显是sqrt 写成了sprt

#include<iostream>

using namespace std;

cout<<"x1="<<x1<<endl;
cout<<"x2="<<x2<<endl;
return 0;
}

要学会看错误信息哦！

#include<iostream>
#include<cmath>
using namespace std;
int main()
{
float a,b,c,x1,x2;
cin>>a>>b>>c;
x1=(-b+sprt(b*b-4*a*c))/(2*a); //sprt是什么函数,应该是 sqrt
x2=(-b-sprt(b*b-4*a*c))/(2*a);
cout<<"x1="<<x1<<endl;
cout<<"x2="<<x2<<endl;
return 0;
}
另外你的程序考虑的好象很简单呀,应该复杂一点,不考虑虚数也要考虑a的情况吧.
